“Astronomers have discovered 128 new moons orbiting Saturn, giving it an insurmountable lead in the running tally of moons in the solar system…

The moons were identified using the ‘shift and stack’ technique, in which astronomers acquire sequential images that trace the moon’s path across the sky and combine them to make the moon bright enough to detect. All of the 128 new moons are ‘irregular moons’, potato-shaped objects that are just a few kilometres across. The escalating number of these objects highlights potential future disagreements over what actually counts as a moon.”
